Combo box to array

[Ken_Naylor]

Also using inset into array does just that 'Inserts' into the array that means the array grows on every loop itteration (again execution highlighting shows this!)  What you need is 'Replace Array Subset' and a shift register .  You also need to initialise your array with the numebr of elements in the combo box before the loop starts.

I have a solution (not elegant) which does what you want - tell me what version of LabVIEW are you using and I will post.

I am using labview 10. It would be great if you can post the solution. 

Thank You

Yes this solution is almost similar to what i need. However, my requirement is to use combo box instead of ring. And the combo box should have values that match the item. Thats the basic twist and the part where i am stuck. 

Can you please guide me how to replicate it for a combo box??

Hi,

I have attached a VI of the code I made. Its very crude and simple. Is there any smarter way to do it? 

Also I have read on many forums about how to disable/gray the controls but I could not find anything about how to disable/freeze the inidcator with a property node.

In my main VI there are two boolean buttons and I want to be able to use them to gray the indicators (i.e. stop updates). How can it be done?

Thanx in advance!!

Hi,

One thing to note about your code is once you switch and element in the array to true it stays true. Meaning if you pick "hi" from the combo box it switch the corresponding element in the array to "true".  If you then pick "bye" it switch that element to "true" but the element for "hi" will remain true.  This may no be desired behavior for you application.  Have you thought of using an enum?

See the attached example for how to disable to indicator.

Hi,

The program is required to retain the true value unless it is stopped (em working on how to reintialize to default after stop via invoke node). 

However, the vi you attached is in labview 11, while I have version 10. can u plz reload it in version 10. Thanx a lot for the help btw.

Hi,

It works. . .and this is exactly what i have been trying (the difference is that i pass data between subvis instead of the same one) but the problem is still there.

When we change the value of the fourth boolean control the indicator LED changes value even when it is disabled. What i want is that when the user disables it, the indicator not only gray out but its value should not change as well.

Is there any way to do it? I tired all possibles ways i can think of. But either they dont work at all or they dont work with the passing reference method i have used (see attachments of my previos reply).

Em getting depressed with each passing day 😞

Hi,

The best way I can think to do that is to break use a shift register and stop data from being written to it when it is disabled.  See attached.
